Title: Improvements in and relating to hydraulic pumping units comprising electric motors of low starting torque
IPC: F04C14/06
Filed: 1950-11-15
Abstract: 695,386. Rotary pumps. BRADBURY & SONS, Ltd., J., and POWELL, V. Nov. 2, 1951 [Nov. 15, 1950], No. 27982/50. Class 110(ii) To relieve the pump-driving motor 2 of heavy loading at starting-up, the pump 3 delivers liquid into a receiver 8 in which the back pressure gradually increases to a pre-determined figure at which a non-return valve 24 is opened to the hydraulic delivery line 23. The back pressure may be secured through air trapped in the receiver or by means of a spring 19, Fig. 2, in a receiver 10. A controlled bleed off from the pump delivery may be secured through a valve 9. Manual operation of a valve 27, through a push-rod 33, allows backflow from the line 23 through a pipe 30. The pump 3, which may be of the gear type, has an inlet 6. Liquid, in a container 1, is preferably at a line x, below the receiver 8. The motor 2, usually of single phase synchronous type, may drive the pump through a chain transmission 4. In Fig. 2, as the pump delivers into a receiver 10, a piston 18 is forced upwards against increasing pressure from the spring 19. The line 23 may lead to a hydraulic ram. The receiver empties after each pumping operation due to the bleed valve, and/or leakage back through the pump.

Title: Improvements relating to electric switches
IPC: H01H33/32
Filed: 1929-09-14
Abstract: 341,499. High - tension switches. RUPPEL, S., 8, Palmengartenstrasse, Frankfort-on-Main, Germany. Sept. 14, 1929, No. 27983. [Class 38 (v).] In switches employing a blast of gas under pressure to extinguish the arc, gas at different pressures are used, the pressure being increased or decreased when the movable contact has travelled a predetermined distance. In the construction shown in Fig. 1, the hollow contact-member 9 serving to bridge the fixed contacts 4, 6 slides in a guide-tube 18 provided with ports. To open the switch, low pressure is supplied through the valve 23 to the upper end of the piston 11 carried by the contact-carrying member. At the same time, the low-pressure supply is admitted to the container 1 and to the insulating chamber carrying the fixed contacts and so through the ports 15 in the movable contact to the neighbourhood of the arc. The valve 23 is interlinked with the high-pressure valve 24 so as to operate the second valve when the opening movement has commenced and admit high pressure, by way of the chamber 19 and port 16, to the interior of the contact-carrying member and so through the ports 14 to the outside of the contactcarrying member. When the contacts further separate, the supply is admitted through the ports 12, 13 of a deflector to the interior. In a modification (Fig. 2 not shown), in which two breaks per phase are employed, the high-pressure chamber leads through a two-way passage to the exterior of the upper ends of the two movable contacts. The high-pressure supply may be generated in the hollow movable contact itself which may enclose a fixed piston. As the contact moves downwards, air is compressed within it and at the moment of break ports at the upper of the contact are opened releasing the compressed air. The high pressure may be generated by the low-pressure gas operating a large piston in the switch cylinder and actuating a smaller piston in the same or in a separate cylinder to compress the gas which is released at break. A separate source of highpressure gas may be employed for the high-pressure supply, and this source may be controlled in accordance with the voltage or current of the circuit.

Title: An electrical device for sensing the angular position of a rotary member
IPC: G01D5/12
Filed: 1959-08-17
Abstract: 913,105. Transformers; selsyn machines. BODENSECWERK PERKIN-ELMER & CO. G.m.b.H. Aug. 17, 1959 [Sept. 24, 1958], No. 27996/59. Classes 35 and 38 (2). A transformer, whose output depends upon the angular position or speed of rotation of a body, comprises a number of primary and secondary windings disposed in a circle and connected so as to eliminate errors due to eccentricity of its parts. As shown in Fig. 1, the windings are mounted on polepieces on a stationary ring, the primaries on poles 1 . . . 4, the secondaries on flanking poles 1a . . . 4a and 1b . . . 4b. A rotor 6 has four ferromagnetic segments A 1  . . . A 4  which divert the flux from each primary pole differentially to the flanking poles. Thus, the difference in output between secondaries in each pair is a measure of the angular position of the rotor. Eccentricity errors are avoided by connecting corresponding windings in series. In an alternative arrangement (Figs. 3 and 4, not shown), there are six primary windings connected in alternate sense round the ring, and there are a like number of secondary windings disposed between them. Each secondary pole then receives flux from the primaries on either side of it, to an extent dependent on the position of the rotor. In the arrangement shown in Fig. 5, the stationary poles 10 carry the primary windings only, again in alternate sense, secondary coils 14 being mounted for rotation between the primary poles and a stationary ferromagnetic ring 12. The output is then at the supply frequency, but modulated in amplitude at a frequency dependent on the speed of rotation of the ring of secondary windings.

Title: Improvements in or relating to liquid moderator nuclear reactors subject to varying movements
IPC: G21C1/08
Filed: 1959-08-20
Abstract: 931,779. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 20, 1959 [Aug. 22, 1958], No. 28492/59. Class 39 (4). [Also in Group XXIX] . In order to compensate for the effect of variation of density of the water-steam mixture in a boiling water reactor on board a ship due to acceleration in a vertical direction imparted to the reactor by the ship motion, the moderator circuit leading from the hot end of the reactor to an energy-utilizing means (e.g. a heat-exchanger or turbine) returns to the reactor via a flow-control means sensitive to the acceleration of the reactor whereby the flow is increased upon a reduction of moderator density and decreased upon an increase of density. As shown, the reactor core 1 is located in a vessel 3 filled with moderator water 2, the steam generated passing through a duct 4 to a heat-exchanger 5, the condensed steam passing through a duct 6 to a reheater 7 where it heats cooling water passing to the secondary circuit (not shown) of the exchanger 5. A duct 8 conveying hot water from the reflector zone of the moderator 2 is connected to the duct 6. The moderator is returned to the bottom 11 of the vessel 3 through a duct 10 by a pump 9, the pump having a by-pass 12 containing the acceleration-sensitive flow control means 13. When the valves 14, 15 are open the control means 13 serves to return to the inlet side of the pump 9 a variable delivery taken from the outlet side, this delivery being a function of the vertical acceleration applied to the control means. Thus, consequent upon an upward acceleration to increase the moderator density, the control means 13 passes an increased flow through the by-pass 12 and a decreased flow of moderator returns to the reactor through the duct 10. To prevent variation in the temperature of the moderator returned to the reactor due to the operation of the control means 13, a proportion of the moderator is returned to the reflector zone by a by-pass 16 and duct 19, this by-pass containing an acceleration-sensitive flow control means 18 similar to the control means 13. The control means 18 varies the flow through the by-pass 16 in a manner equal and opposite to the variation through the duct 10. The control means 13, 18 comprise a valve operated by acceleration-sensitive masses and are described in detail with reference to Fig. 2 (not shown, see Group XXIX).
